## Abstract Poly(ester‐urethane)s (PUs) were synthesized using hexamethylene diisocyanate (HDI) or toluene diisocyanate (TDI) to join short chains (__M__~n~ = 2000) of poly(R‐3‐hydroxybutyrate) (PHB) diols and poly(ε‐caprolactone) (PCL) diols with different feed ratios under different reaction cond

## Abstract A series of poly(R‐3‐hydroxybutyrate)/poly(ε‐caprolactone)/1,6‐hexamethylene diisocyanate‐segmented poly(ester‐urethanes), having different compositions and different block lengths, were synthesized by one‐step solution polymerization. The molecular weight of poly(R‐3‐hydroxybutyrate)‐d
## Abstract The objective of this study was to prepare high molecular weight poly(ester‐anhydride)s by melt polycondensation. The polymerization procedure consisted of the preparation of carboxylic acid terminated poly(ϵ‐caprolactone) prepolymers that were melt polymerized to poly(ϵ‐caprolactone)s
